The US government has handed back $81 billion in tariff refunds this fiscal year after the Supreme Court ruled that key tariffs imposed under President Donald Trump’s International Emergency Economic Powers Act authority were, in fact, illegal. That is not a typo. Eighty-one billion dollars, roughly the GDP of Luxembourg, flowing back to importers who were overcharged under a trade policy the nation’s highest court just torched with a 6-3 decision.
To put that number in perspective, the government refunded just $5 billion in tariffs during the previous fiscal year. The 16x spike landed almost entirely in May and June 2026, immediately following the court’s ruling. The Treasury has confirmed the surge ties directly to the decision.
What happened, and why it matters now
The Supreme Court’s ruling struck down tariffs that Trump had imposed using IEEPA, a statute traditionally reserved for genuine national emergencies rather than broad trade policy. The court’s majority found that the executive branch had overstepped its authority. Six justices agreed. Three did not.
The practical fallout has been swift. Importers who paid duties under the now-invalidated tariffs have been lining up for refunds. Companies ranging from FedEx to Costco have pursued claims, with Costco notably involved in class-action litigation seeking to pass refund savings along to its members.
